Abstract: Embodiments presented herein are generally directed to a stimulating assembly of a cochlear implant. The stimulating assembly comprises one or more fixation features configured to be inserted into a recipient's cochlea via an opening in the cochlea. Following insertion, the one or more fixation features are configured to engage an inner surface of the cochlea adjacent to the opening to prevent movement of the stimulating assembly out of the cochlea through the opening.

Abstract: A method of forming an electrode array is disclosed, the method comprising: forming an elongate comb structure comprising a plurality of longitudinally-spaced electrode contacts extending from and supported by a spine; electrically connecting each of a plurality of electrically conductive pathways to a respective one of the plurality of electrode contacts; placing the conductive pathways adjacent the contacts; placing silicone over the conductive pathways and contacts; curing the silicone so as to substantially retain the longitudinal spacing between neighboring contacts; and severing the spine from the plurality of electrode contacts.

Abstract: An implantable electrode assembly. The electrode assembly comprises an elongate carrier member, at least one electrode contact disposed in the carrier member, and at least one elongate conductive pathway disposed in the carrier member having a distal end attached to the at least one electrode contact and having a substantially planar strain relief formed therein that is located only in the distal region of the at least one pathway.

Abstract: An imaging assembly is provided comprising an x-ray tube housing having a tube mounting hub and formed from a lightweight material. A rotating gantry assembly includes a gantry mounting surface adapted to engage said tube mounting hub. A plurality of barrel nut fasteners secure the tube mounting hub to the gantry mounting surface while reducing stress in said x-ray tube housing.

Abstract: A system for monitoring a communication network for actual and potential network problems is provided. The system includes a communication tracking module to track network communications between at least one network-user device and a network service provider device during a predefined time interval. The network communications are based upon a user-supplied indication of a network problem. The system also includes a report generating module to generate a report based upon the network communications tracked, and a threshold determination module to determine whether the number of network communications exceeds a predetermined threshold.

Abstract: A cooling system to cool the x-ray tube of a CT imaging system. The heat exchanger has a curved sector shape which provides a larger surface area for heat dissipation within the cover of the gantry. The axis of the cooling fans is preferably parallel to the rotational axis of the gantry.

Abstract: An imaging tube coolant volume control system (14) for an imaging tube (18) includes a compensation tank (80) that is configured to fluidically couple an imaging tube cooling circuit (11). The compensation tank (80) includes a cooling fluid (17) and a compensation-dividing member (100). The member (100) is adjustable in response to the change in volume of the cooling fluid (17). An overflow vessel (82) is fluidically coupled to the compensation tank (80). A compensation valve (86) is coupled between the compensation tank (80) and the overflow vessel (82) and allows flow of the cooling fluid between the compensation tank (80) and the overflow vessel (82) when pressure of the cooling fluid (17) is greater than or equal to a first predetermined pressure level.

Abstract: An energy-absorbing device (78) for an imaging tube (18) includes an energy-absorbing body (82). The energy-absorbing body (82) is fluidically coupled to a housing (60) of the imaging tube (18) and absorbs the kinetic energy generated within the imaging tube (18). The kinetic energy may be generated from the separation of material fragments from a rotating target (74) within the housing (60).

Abstract: The present invention includes a cast in place aluminum tailspout and a stainless steel exhaust pipe. The stainless steel exhaust pipe includes a flared out portion. The cast in place tailspout includes a section that surrounds at least a portion of the flared section of the exhaust pipe and includes a hooked finger for engaging an outwardly extending shoulder of the flared portion.

Abstract: The present invention provides specific genetic deletions that result in an avirulent phenotype of a mycobacterium. These deletions may be used as phenotypic markers of providing a means for distinguishing between disease-producing and non-disease producing mycobacteria.

Abstract: This invention relates to a method of quantifying bacteria in vivo or in vitro using bacterial reporter strains. In particular this invention provides a method utilizing mycobacterial reporter strains that permits rapid screening for in vivo antimycobacterial activity of various compositions. In addition this invention provides for particular mycobacterial reporter strains expressing the FFlux gene at levels sufficiently high to allow detection in tissue homogenates without lysis or concentration of the bacteria.

Abstract: Novel nitrogen- and sulfur-containing amphoteric compounds are prepared by reacting ammonia with a heterocyclic intermediate prepared from a nitrile, an olefin and sulfur trioxide. These compounds are useful as surfactants; those that are polymerizable form polymers which are useful as co-flocculants in combination with inorganic flocculants.
